IMAGACT4ALL: Mapping Spanish Varieties onto a Corpus-Based Ontology of Action.
Full text linkIMAGACT is a corpus-based ontology of action concepts, derived from English and Italian spontaneous speech resources, which makes use of the universal language of images to identify action types. IMAGACT4ALL is an Internet infrastructure for mapping languages onto the ontology. Because the action concepts are represented with videos, ex- tension into new languages is done using competence-based judgments by mother-tongue informants without intense lexicographic work involving underdetermined semantic description. It has already been proved on Spanish and Chinese and it is now in the process of being extended to Hindi, Bengali, Sanskrit, Urdu, Oriya, Polish, European and Brazilian Portuguese. IMAGACT4ALL has also been successfully used to implement language varieties, as European and American (Argentinian) Spanish. The first part of this paper presents the infrastructure and the methodology for mapping languages onto the ontology. In the second part we present the results of a comparative analysis of European and American Spanish data derived from the database, that show relevant distinctions in the referential properties of the Spanish verbal lexicon in the two language varieties
Diacronia e sincronia delle polirematiche con struttura preposizionale: un’analisi su corpora
No full textQuesto lavoro intende chiarire le dinamiche di lessicalizzazione e grammaticalizzazione che hanno condotto alla formazione di polirematiche con la struttura di sintagmi preposizionali in italiano contemporaneo, a partire dall’analisi delle configurazioni in latino e nelle fasi più antiche di lingua. Nell’analisi si intende (a) fornire un quadro rappresentativo delle configurazioni in latino, in italiano antico e in italiano contemporaneo, (b) chiarire il rapporto diacronico tra configurazioni che impiegano gli stessi lessemi, (c) mettere in luce le divergenze generali interne al sistema delle polirematiche con struttura di sintagma preposizionale. Nell’analisi della trafila diacronica che ha condotto alle configurazioni contemporanee, viene infine analizzata l’evoluzione delle diverse funzioni, individuando un percorso storico che ha portato alla diversificazione funzionale del sistema delle polirematiche preposizionali in italiano
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
IMPAQTS: un corpus di discorsi politici italiani annotato per gli impliciti linguistici
No full textIl contributo presenta il corpus multimodale di discorsi politici italia-
ni IMPAQTS e lo schema di annotazione pragmatica ad esso applicato. Il corpus è costruito per essere rappresentativo del linguaggio politico della Repubblica italiana: nel contributo se ne descrivono i criteri di bilanciamento e i metadati. Il corpus è inoltre annotato per contenuti discutibili veicolati implicitamente. Dello schema di annotazione pragmatica si illustrano i presupposti teorici e i correlati applicativi. Infine, si forniscono alcune indicazioni qualitative e quantitative emerse dall’analisi di una prima tranche di 477 discorsi annotati
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
